IMPROVEMENT IN CAR-COUPLlNGS.

Specification forming part of Letters Patent No. 165,857. dated July 20, 1575; application tiled May 6, 1875.

To all whom. it may concern Be it known that I, LEWIS E. MUsIeK, of Wellsville, in the county ot' Montgomery and iu the State of Missouri, have invented certain new and useful Improvements in Car- Uouplers and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings and to the letters of reference marked thereon, making a part ot' this speciiication.

rlhe nature of' my invention consists iu the construction' and arrangement ot' a car-coupling, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which niy invention appertains to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawing, in which- Figure l is a plan view oi' my car-coupling, and Fig. 2 is a longitudinal vertical section of the same.

A represents part of the frame-work'of a railroad-car, in which the draw-bar or drawhead B is attached in any of the known and usual ways.

At the front or outer end of each drawhead B, on the sides, are formed wings or tlanges C U, projecting, one at the top and the other at the botto1n,a suitable distance in front ot' the draw-head. These wings or lianges are curved or beveled in such a Inanner that when two draw-heads come together the lia-uges will ride on each other, and adjust the draw-heads to the proper height.

In each draw-head B is placed a sliding block, l), which is connected through a slot in the bottoni ot' the draw-head, by moans of a rod, a, with a lever, E, pivoted at some convenient part of the frame A, and projecting beyond the side of the car. The lever E is, by a rod, b, connected with a vertical rod, G, passing through suitable guides on the front of the car to the top thereof. The rod b, which connects the lever E and rod Gr, is bent somewhat in V form, one end being attached to the lever and the other to the carfraine A, while the rod Gr is attached thereto at the angle. By these means the block D may be moved forward or backward, as desired, in the draw-head, either from the side or the top of the car.

To the front side of the sliding block D is connected the coupling-link d by means of a link, e, formed on the inner end of the coupling-link and fastened by a staple, f.

The coupling-pins II used in my car-coupling are made in the form of a letter U inverted, with the rear prong h1 extended below the end of the other arm or prong' h2 Between the two arms of the coupling-pin in the bottom of the draw-head is pivoted a latch, h, the upper end of which extends up intoa groove in the root of the draw-head, and when the coupling-pin is raised this latch falls forward under the arm h2 of the coupling-pin, and holds the same in an elevated position. In the end of the long arm h1 of the coupling pin is inserted a pin or key, li, which prevents the conplingpin from rising higher than is necessary to allow the latch to l'all forward under the short arm h2 thereof.

To couple the cars the links are thrown forward by means ofthe lever arrangement connected to the sliding block D. The links, eutering the opposite heads, force the latches h h back, so that the coupling-pins will drop, their arms h2 passing through the links.

To uncouple the cars the coupling-pin is raised, the links dropped back by the weight ot' the levers and lifting-rods, and the latches drop forward to their places oftheirown weigh t, holding the coupling-pins in position again.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A draw-head, B, provided with projecting curved or beveled side flanges C U, substantially as and for the purposes herein set forth. 2. The combination, in a car-coupling, of the sliding block D, with the couplinglink d connected thereto, the rod a, lever E, bent rod b, and lifting-rod G, all substantially as and l'or the purposes herein set forth.

3. The self-actin g gravitating-latch h, pi voted to the bottom of the draw-head, in combination with the U-shaped pin H, all substantially' as set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 6th day of April, 1875.
